Key operated on the outside and thumb turn knob on inside.
ABS QUANTUM THUMBTURN LOCKS ALLOW EASY EXIT IN CASE OF AN EMERGENCY AND ITS EASY INTERNAL LOCKING AND UNLOCKING FUNCTION MEANS YOU ONLY NEED TO USE THE KEY WHEN LEAVING AND ENTERING YOUR HOUSE. RECOMMENDED BY EMERGENCY SERVICES.
These thumbturn cylinders can be ordered keyed to your existing ABS key number or keyed alike to other cylinders.
If you require more than one cylinder to be operated by the same key, or require cylinder(s) to match an existing key, please order Keyed Alike ABS Euro Key And Turn Thumbturn Cylinders here.
We strongly advise you to contact your insurer before installing thumbturn locks, as some may not accept them. (Note - xx/30mm EXT sizes do not comply to BS-TS007:2012 3 star due to the cylinder having 6 combination pins, compared to 8 in all other sizes).
ABS Thumbturn cylinders should not be used on locks with a night latch function i.e. where door locks automatically when closed (as a lock out may occur). An ABS double cylinder should be considered instead.
Care should be taken when using the ABS thumbturn cylinder. The thumbturn is spring loaded to comply with the new TS008 maximum security standard, this is a security feature whereby the thumbturn cannot be "fished" to unlock the door from outside. THE THUMBTURN MUST BE PUSHED IN TO TURN AND MUST BE RELEASED BACK TO ITS ORIGINAL OUT POSITION AFTER EVERY OPERATION: This is a design feature to ensure that the lock is always in the correct position to resist external attack. IF THE THUMBTURN IS LEFT IN THE MIDWAY POSITION (IE: THE SPRING MECHANISM HAS NOT RELEASED) YOU WILL ENCOUNTER A PROBLEM INSERTING THE KEY FULLY FROM THE OUTSIDE.
On a lever outside / lever inside operation door this means that you could be locked out if a member of your household has locked the door from the inside and not returned the thumbturn to the correct position.
On a pad outside / lever inside operation this means you could lock yourself out of your home if you do not return the thumbturn to the correct position on opening the door, and the door closes behind you. In this instance we recommend an ABS double cylinder should be installed.
As these ABS cylinders are specially ordered in from Avocet on demand, we cannot accept return of them if you decide they are no longer required. Please allow 7 - 10 days for delivery of thumb turn cylinders.
